I have the Berry and Krieg Dobsonian book ...and plan to follow their designs
closely. Recent discussions here have convinced me to research a mirror cell
different than they recommend.

What else has changed since the book was written?

The book was written with success in mind.  That is, the designs presented
are conservative with ample room for error.  Nothing has changed - the
book's designs were fairly conservative when it was first published, and
they remain so today.

It's a great book and I highly recommend it.

Well said!

But, even the best books should be read with an appropriate amount of
skeptisism, as a good practice. I take for example their sling fixation
that
I deeply dislike. That being said I have learned quite a lot of good things
reading this book.
